Windows Vista offers a considerable number of new and improved features over Windows XP. Some of these great new features include:

Windows Aero: Windows Vista features a totally different look for its interface—a cleaner, transparent look with impressive graphic quality, not to mention Live Icons and the new Windows Flip 3D feature. Windows Aero requires a higher-end video graphics card; otherwise, Windows Vista is displayed using Windows Basic. Check with your computer manufacturer, or use the Windows Vista Upgrade Advisor to see whether your video card is ready for Windows Aero.

Windows Sidebar: Windows Vista offers a panel (transparent, if you're using Windows Aero) that displays your selection of Windows gadgets—mini-applications that perform useful functions, such as a clock, a calendar, a Microsoft Office Outlook inbox representation, and currency exchange.

Microsoft Windows Media Player 11: While you can download it for Windows XP, this latest and greatest version of Windows Media Player is designed for Windows Vista and shouldn't be missed. With its new graphics-oriented interface, Windows Media Player 11 abandons the text-oriented look and field of previous versions. Did I mention that you can also use Windows Media Player 11 to share your media over your private home network?

Windows Search: One of the most helpful new features in Windows Vista, you can now search for files or applications from almost anywhere. Unlike in Windows XP, with Window Search, you can simply type a few letters of your search request, and the results appear on the fly—a helpful feature when looking for a file or application from the Start menu. For example, type fir, and Windows Firewall entries appear in the Start menu.
